Vancouver, BC — Sabina Gold & Silver Corp (SBB.T) is pleased to announce additional assay results from holes drilled as part of the 2011 exploration program on its Umwelt and Llama deposits at the Goose property and the first results from exploration drilling on the George property at its 100% owned Back River Project in Nunavut, Canada.

The 2011 drilling campaign at Back River started on the Goose claim block in March. The focus of work is to extend and expand the new deposits at Umwelt and Llama and to identify new deposits. There are currently eight drills operating at Back River. Five rigs are in the Goose area, where two are shifting focus from resource expansion to focus on the numerous untested discovery targets within the 5 km corridor containing the Goose, Llama and Umwelt deposits. One rig continues at George and two rigs are soon to be operating on the Wishbone properties testing gold targets on those claims retained by Sabina after the Hackett River transaction.

Results continue to demonstrate that Umwelt is a strong, well mineralized system with good continuity and grade. Based on last year’s drilling, the Company reported indicated resources at Umwelt of 4.6 m tonnes grading 6 g/t Au for a total of 900,000 oz and an additional inferred resource of 980K tonnes grading 6.4 g/t Au for a total of 221,000 oz over a strike length of 550 metres.

In 2011 one drill is completing 100 m step out holes tracing Umwelt to the south, with two drills following up behind with infill holes. Most significantly, Hole 11GSE042, the furthest hole to the south in which assays have been returned, intersected10.54 g/t Au over 10.3 m including 16.70 g/t Au over 3.4 m. This hole is 550 m south of the drilling completed in 2010 and extends the overall strike length of the deposit to over 1.2 km. It is at a vertical depth of 550 m. The deposit continues to remain open along strike and to depth and plunges at a consistent 25 degrees. Other highlights include Hole 11GSE037which returned 8.71 g/t Au over 25.2 m including 18.98 g/t Au over 5.5 m, located approximately 300 m to the south of the drilling that was completed in 2010. This intersection is at a vertical depth of 420 m.

“We continue to extend and add to the Umwelt deposit at the Goose property,” said Tony Walsh, President & CEO “the system remains open and we continue to see the structure, mineralization and visible gold as we keep drilling the deposit at depth to the south. There remains excellent potential for Umwelt to continue to grow and add ounces. Also, our Exploration Tool Box is proving successful on other areas on the property. At the George claim block, the application of the tool box has yielded very encouraging prospects for new large scale open pitable discoveries. Additionally, the sale of the Hackett River Project to Xstrata Canada Zinc has also enabled us to focus entirely on looking for new gold discoveries on our retained claims on the Wishbone greenstone belt. A drills and crew have been mobilized and work has begun on the south east portion of the belt adjacent to Back River”

To date, at Back River a total of 82 holes and 28,700 metres of core have been completed, or are in progress, with many assays still pending. A total of five rigs are currently drilling on the Goose claim block generating approximately 325 m of core per day.

The deposits and target areas at the Goose claim block are within a 5 km corridor that have been identified using an exploration system developed by Sabina’s geological team. This new Exploration Tool Box is based on a set of assumptions that specifically target large buried alteration and mineralized features in folded iron formation units that have the potential to be extracted by open pit methods.

Application of the Exploration Tool Box is also in progress at the George claim block. George contains a current indicated resource of 1.84m tonnes grading 10.9 g/t Au for a total of 590,000 oz and an additional inferred resource of 2.6 m tonnes grading 10.5 g/t Au for a total of 866,000 oz of. The current deposits at George are mainly amenable to being mined by underground methods; however, with the development and application of the new tool box, numerous opportunities to find additional large shallow open pit deposits in the area have been identified.

Work has focused on one relatively underexplored area to-date and this work has resulted in a number of encouraging new discoveries. For example, at the Trigger target, silicified and sulphidized breccia zones in sediments associated with iron formations have returned a number of strong intercepts including 9.12 g/t Au over 6.00 m in hole 11GRL001. Most assays from George are still pending.

UMWELT

To date a total of 22 holes totalling 12,500 m have been drilled or are in progress on the Umwelt zone at the Goose property.

Drilling at Umwelt has effectively extended and expanded the mineralized zone both along strike and down plunge. At this time, the Umwelt zone mineralized trend has been traced over a strike length of 1.2 km and down to a vertical depth of 550 m below surface. The zone remains open both along strike and to depth.

The mineralized zones are hosted within a turbiditic sedimentary sequence containing silicate and oxide facies iron formations. Gold dominantly occurs with quartz +/- carbonate veining and arsenopyrite +/- pyrite +/- pyrrhotite in the iron formation. Drilling at Umwelt has identified an anti-form structure with a fold hinge that plunges to the south at 25 degrees. Thick zones of gold mineralization are associated with the fold hinge in what is now known as the Main Zone. Mineralization also occurs along a separate iron formation horizon immediately to the west known as the West Zone. The relationship between the Main and West zones is uncertain but the West Zone may be a refolded limb of the Main zone.

GEORGE CLAIM BLOCK

To date, a total of 29 holes comprising 5,672 m have been completed or are in progress at George.

Sabina continues to experience a high level of exploration success, demonstrated by some encouraging results at the Company’s Trigger discovery located on the George Property. The first hole of the diamond drilling program confirms a significant gold endowment at this target and validates the company’s exploration strategy. Numerous gold intercepts were returned within hole 11GRL001 (Trigger) including; 9.12g/t Au over 6.00 m, 1.87g/t Au over 8.00 m, 4.37g/t Au over 1.00 m, 2.45g/t Au over 1.00 m, 2.11 g/t Au over 1.00 m and 7.99 g/t over 0.50 m within brecciated, silicified and sulphidized sediments associated with oxide iron formation.

Target areas for priority testing at George in 2011 include the Bullwinkle, Rifle, Trigger, Lookout Hill, Shadow Pond and NZ locales, all of which are identified as having geological, geochemical, and geophysical attributes analogous to the deposits at the Goose claim block. Diamond drilling of this area is 100% focused on looking for new shallow open pit discoveries. Assays are still outstanding for much of this drilling.

One drill continues to test the targets at George.

LLAMA DEPOSIT

Initial drilling at Llama focussed on minor gaps in the resource model and attempting to extend and expand the mineralized zone both along strike and down plunge.

To date, a total of 27 holes totalling approximately 8,700 m have been drilled or are in progress on the Llama deposit. Many assay results are still pending. The deposit has been challenging to expand, as it has a complicated structure marked by faulting and displacement of the host iron formation to the south.

Noteworthy results from the drill program include Hole 11GSE035, which returned 8.79 g/t Au over 5.0 m on the East Limb.

GOOSE DEPOSIT

A total of 3 holes totalling 590 metres were drilled on the Goose deposit. The holes were drilled to provide information for the ongoing geological / resource modelling interpretation in support of an open pit resource estimate. No additional holes have been collared on the Goose deposit.

The open pit resource estimate is currently underway.
